40x10-18

40x10-18 ATV/UTV tires are built for machines running 18 inch wheels where tire height, width, and tread choice all matter. The 40 inch height creates a large tire package for custom UTV and side-by-side builds, while the 10 inch width helps balance traction, stance, and clearance. This size can work well for custom UTV builds, lifted side-by-sides, large-wheel off-road setups, and fitments where height, clearance, and stance are major factors, depending on tread pattern, load requirements, and how the vehicle is used. The wider footprint can support traction and stability when the wheel width, offset, and suspension clearance are a proper match. Before ordering, compare your current sidewall size, confirm the 18 inch rim diameter, and check whether the tire belongs in a rear, wider replacement, trail, or machine-specific position. Getting the fitment right helps protect handling, clearance, traction, and the way your machine feels on the trail.
